NCT01562288

Brief Summary

RATIONALE: Studying samples of blood and DNA in the laboratory from patients who received chemotherapy with or without trastuzumab may help doctors learn more about the effects of trastuzumab on cells. It may also help doctors understand how well patients respond to treatment. PURPOSE: This research trial studies blood and DNA samples from patients with breast cancer treated with chemotherapy with or without trastuzumab.
